Ivankovo Hydroelectric Plant. The Ivankovo Hydroelectric Plant is a pioneering run-of-the-river power station located on the Volga River in Moscow Oblast. Completed in 1937 as part of the ambitious Soviet Union electrification drive, it was the first major hydroelectric facility on the Volga and created the expansive Ivankovo Reservoir, a critical water source for Moscow. The plant's construction marked a significant milestone in the GOELRO plan and the development of the Volga-Kama Cascade.

History

The project was conceived under the First Five-Year Plan as a direct implementation of Vladimir Lenin's GOELRO plan for nationwide electrification. Initial surveys and planning were conducted by engineers from Gidroproekt, the premier Soviet hydroelectric design institute. The decision to build on the Volga River near the settlement of Konakovo was strategic, aiming to provide both power and a reliable water supply for the growing capital, Moscow. Its completion in 1937 preceded larger projects like the Uglich Hydroelectric Station and the Rybinsk Hydroelectric Station, establishing a template for subsequent developments along the Volga and across the Soviet Union.

Design and construction

The design was led by prominent Soviet engineers, including those from Gidroproekt, who employed a run-of-the-river scheme to minimize flooding. The primary structure is a concrete gravity dam integrated with a powerhouse and spillway sections. A key feature of the project was the creation of the Ivankovo Reservoir, often called the "Moscow Sea," which required significant land alteration and the relocation of several villages. Construction, managed by the state trust Volgostroy, began in 1933 and utilized a large workforce, including Gulag labor, amidst the challenging conditions of the Great Purge. Major equipment, such as Kaplan turbines and generators, was supplied by domestic manufacturers like the Leningrad Metal Plant.

Technical specifications

The facility has an installed capacity of approximately 30 MW from multiple Kaplan turbine units. The associated Ivankovo Reservoir has a surface area of 327 square kilometers and a volume of 1.12 cubic kilometers, making it a substantial artificial lake. The concrete gravity dam stretches for roughly 9 kilometers, including its ancillary structures. The plant's average annual electricity generation is about 100 GWh, which is fed into the regional grid operated by MOESK. The complex also includes crucial navigation locks that facilitate passage along the Upper Volga.

Operational history

Upon its inauguration in 1937, the plant immediately began supplying electricity to the Moscow grid and regulating water flow for the Moscow Canal. It played a vital role during World War II, providing power for the defense industry in cities like Tver and Klin. Throughout the Soviet era, it was administered by the Ministry of Energy and Electrification of the USSR and later became an asset of Unified Energy System. Following the dissolution of the Soviet Union, it was transferred to the state-owned generation company RusHydro. The station has undergone several modernization campaigns, including turbine replacements in the 2000s, to maintain efficiency and safety standards.

Environmental impact

The creation of the Ivankovo Reservoir significantly altered the local ecosystem, leading to the submersion of forests, wetlands, and agricultural land, which affected species composition. It serves as the primary source of drinking water for Moscow, managed by Mosvodokanal, necessitating strict water quality controls. The reservoir has also become a significant site for recreational activities, including boating and fishing, around towns like Dubna. Long-term concerns include siltation, eutrophication, and the impact of water level fluctuations on shoreline stability, which are monitored by agencies like Rosprirodnadzor.
